Energizer Series CR Button Battery, 3V Nominal Voltage, 620mAh Capacity - 7638900381795

This button battery is a 3V lithium coin cell designed to power small electronic devices that require a stable low-current supply over long periods. It uses a lithium/manganese dioxide chemical system and is supplied as a two-cell pack for applications needing spare or multiple batteries. The cell is suited to environments with broad temperature ranges and low self-discharge for extended shelf life.

Features and Benefits:

• 620mAh typical capacity delivers extended service life
• Flat termination enables compact, low-profile installations
• Operating range −30°C to 60°C supports varied environmental use
• Self-discharge ≈1%/year preserves stored charge over time
• Background drain 0.39mA at 2.9V maintains low continuous load

Applications

• Suitable for watches and small timing devices
• Used with key fobs and remote sensors
• Ideal for medical monitors and glucose metres
• Can be used for memory backup in electronics
• Suitable for coin-operated metres and security tags

What is the typical mass and energy density of the cell?

The cell weighs 6.8 g and has energy densities of 183 mW·h/g and 647 mW·h/cc.

How does the cell behave under Pulse discharge conditions?

Under 2 s pulses 12 times/day with a 300 Ω load it delivers about 9.0 mA at 2.7 V during pulses.

What is the maximum allowable reverse charging current?

Reverse charging is limited to a maximum of 1 μA.

How long will the cell last under a continuous 7.5 kΩ load at 21°C?

Under a 7.5 kΩ continuous load it provides service for approximately 1590 hours to a 2.0 V cut-off.

What is the typical lithium content and safety consideration for ingestion?

Typical lithium content is less than 0.3 g and ingestion can cause severe injury, seek immediate medical attention if swallowed.
